## Sign
|

|
|
|
||
|
|
### Instructions
|
||
|
|
|
||
|
|
Create the `sign` function that takes one number argument
|
||
|
|
and return 1 if the number is positive, -1 if the number is negative
|
||
|
|
and 0 if the number is exactly 0
|
||
|
|
You must not just use `Math.sign`, make your own.
|
||
|
|
|
||
|
|
Create the `sameSign` function that takes 2 numbers as arguments and check
|
||
|
|
if they both have the same sign
|
||
|
|
|
||
|
|
|
||
